- 2018 Mazda CX-5 GT
It turned extremely cold (-31C) here a week ago and my 2018 CX-5 GT started running extremely rough during startup and acceleration. I discussed this issue with a few people who had the same problem on another Mazda forum. Here is a copy and paste of my final reply on that forum...
They ended up changing my rear engine mount. Only took about 30 minutes to complete. I talked to the service manager and he told me that they changed quite a few of these over the past week or so. He said they got a notice from Mazda head office about this problem a few days ago. Turns out that since the introduction of the 2017 CX-5, Mazda in an attempt to make a quieter Vehicle, Mazda changed these mounts from rubber to some kind of gel fill. When it goes below -30C this gel gets hard and cracks. He said they replaced mine with a rubber mount so that this won't happen again. I won't know for sure until it gets cold again. Right now its only about -20C and the car was warm from being in the shop. According to the shop invoice the new part is KN3L-39-040. Hope this helps anyone who has engine vibration and lives in a northern climate.
